"The present invention relates to a device for use with printing presses for coupling a press and its drive a transportable sheet feeding device by means of coupling members which are arranged on 'the press and on the feeding vice :and engage with one another during thecoupl-ing'operation. v

"The principal object ofthe inventlon 1s to provide means whereby, when the feeding dey vice is bronght to the pressfihe coupling members Which are adapte'cl to engage with one a noth'er automaticallyguide and adjust the sheet feeding device and raise the latter by turning it around its rear Wheels into such a position that the coupling members for the drive of the pressand the feeding device are located opposite to one another in the position of readiness for effecting the coupling operation. For this purpose swinging lugs or i arms carrying bearing members are arranged g Re'fer "g toTF-"gures numeral denotes the framework of a printing ipness, ofnvhich only t he fronti'part is' "shown, ian'd the reference numeral 2 denotes on the press, which lugs guide-the ooup1ing members of the feeding device and raiseit into the coupling positiom the said lugs resting the coupling position against-stops provided in the framework of' the press. In

addition to this, air supplynozzles and electrical contacts adapted to engage with one anotheri'n the coupled position ofthedev-i c'e are provided on the press and on the feeding device, so that when the feeding device and the press are brought together the Various conduits and electrical connections of the feeding; device and of the press are automatically connected 'v'v-ith-one another. By 'means; of

the invention'the resultis attained that by inerel yfbringing the feeding device up to the press the drivinggear; the supply conduits "and the electrical connections of the feeding device and the press are coupled with one 0 another in-readiness for working operations and that likewise by inerdly'moving the feeding'device away from the press again the driving gear, the conduits and the connections are uncoupled :t:('om oneanother.

G11 the front tofithe framework def the press a [bearing bracket 3 is fixed by means :of screws, whichtbeazring bracket is I provided 'ivzith two bearings 55,1 56 in which a a shaft 7 is j'ourna11edf. The bearing bracket 7 is so constructed that the 'paTtdOcated-between the bearings F5; 6"forms a:g1uardfi8 for "1 1 is rigidly fixed.

The bearing bracket 3 {provided vvith an lattachmentzi-n the form of aneyelet in which" an axle '12 is fixed on Wihieh,'oin 'Ibothsides' of "the saidbearing bracket, lugs 13 are mounted, the freev ends of WhiChLa-re shaped so as a cheiinwheel 19 mounted on the shaft 7 ,'the i to constitute ibearing members lt. Previous to the operation of couplin gthe feeding device with the press, the saidlugsJl-3 are brought into the'position -shoWn inj-'Fig. 1, in which they are held firmly inposi'ti'on by means of a stop 1 5resting against the bearing bracket 'In the-1 framework 2 o fthe feedingdevicetwh-ich is -mountedron rollers 16 so as to be transportable, a stub shaft 17 is journalled, which, in the coupled position of the apparatus, is co-axial with the shaft 7 and is provided with a displaceable coupling member 18 corresponding to the coupling member 11 provided on the shaft 7. In the framework of the feeding device a transverse member 19 is also provided to which a forked guide member 21 is fixed by means of screw bolts 20, the space between the arms of the fork of the said member 21 serving for engagement with the guard 8 which is likewise constructed so as to constitute a guide member. For this purpose the arms of the forked guide member 21 are bevelled on their inner sides at the ends and the guard 8 is similarly bevelled on its outer sides. The arms of the forked guide member 21 are also provided with forks located perpendicularly to the horizontal fork of the said member. During the coupling operation the bearings 5, 6 provided on the bearing bracket 3 fixed to the framework of the press engages with the forks provided on the aforesaid arms.

which is furnished with a prolongation 23 [likewise .adapted to co-operate with one of the bearing members 14:. The. pin 22 and the prolongation 23 are arranged on the framework 2 of the feeding device at such a height that, when the feeding device which is laterally guided with regard to the press on the one hand by means of the forked member 21 and on the other hand'by means of the guard 8, is brought up to the press, the said pin and prolongation engage with the bearing members 14 arranged on the lugs 13 which are in the initial position illustrated in Fig.

1. When the feeding device is brought up to the press the lugs 13 are turned backwards and thereby raise thefront part of the framework of the feeding device until such time as they have passed through the vertical position after which they lower the front of the yfeeding device again, the guide member 21 beingmeanwhile moved downwards over the guard and the position of the. feeding device with regard to the press being automatical- 1y adjusted laterally. At the same time the forks at the ends 'of the arms of the guide member 21 engage with the bearings 5, 6 of the bearing bracket 3. The turning movement of the lugs 13 ceases when the stops 27 provided at their upper ends come to rest on thefront of the framework 1. In this position the pin 22 and the shaft 17 of the feeding device are located co-aXially with the .shaft 7 of the press and the coupling mem- 1 bers 11, 18 arelocated opposite to one another in the position requisite for efiecting; the couon the framework of the latter.

pling operation. In order to carry out the coupling operation the coupling member 18 is now displaced so as to bring it into engagement with the fixed coupling member 11. In order to ensure that the apparatus should be in the correct relative positions for effecting the coupling, i. e. that the devices appertaining to the pressand' the platen should be in the necessary relative positions for the working operations, the coupling members 11, 18 are so constructed that the coupling operation can only be efi'ected in one definite position of the'said members with regard to one another. In the constructional example illustrated the claws and recesses of the coupurpose, been During the cooling operation the nozzle passes into the socket 25, asa consequence of Which the air conduit of the press is simultaneously connected with the air conduit of the feeding device during the said coupling operation.

In similar manner can be established between the feeding device and the press automatically by means of suitable contacts. I

The lugs 13 may, of course, be arranged on the sheet feeding device instead of on the press in such manner that when the feeding device is brought upto the press they rest t will also be understood that the lateral guiding devices and the devices for coupling the air conduits may'also be similarly reversed.

Instead of the lugs 13, inclined guide tracks provided at the end with a stop member may also be provided.

In the modification shown in Figs. 4 and 5, a coupllng member 56 1s arranged laterally on the framework 1 of the press, the, sa d coupling member having a suction conduit 28 and a pressure air conduit 29 connected; to it. The coupling member 56 1s provlded with a corresponding suction air conduit 30 and a pressure air conduit 31. In each of these conduits a closing and throttling member 32 and 33 respectively are arranged. The coupling sockets of the conduits 30, 31 are each provided with packing 34-. On the framework of the sheet feeding device a coupling vmember 35 carried on a support 36 is provided, the said coupling member being provided with a suction conduit 37 and a pressure air conduit 38. The ends of both of .these conduits are cut off flush or are like wise provided with packing members adapted to rest flush up against the packing m-em ybers provided on the coupling member 56 51.7

The suction conduit 37 is provided laterally witha branchkoonnectron I39 which is connected to a suction feed- "ing roller 40 by means of a pipe 41 and the pressure air conduit 38 'is provided laterally with a branchconnectison 42 for a pipe 43 which is connected to blast nozzles :arrang ed ongthe :sheet pile stops The suction conduit '3( is' fu'rther provided with an opening leading into the open air,
